It can be tricky under pressure. Definitely prepare beforehand. I declined in the end, the living allowance for a national UNV with experience are too low and not sustainable.

5 interviewers with 5 questions, from demonstration of the understanding of the position, to motivation and related skills connecting to the job requirements. The interview was conducted online. The process was chill and relaxing.
